Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electrical connection, especially relates to a solid fish eye terminal for automobile. BACKGROUND

[0002] The fish eye terminal is a type of press-fit terminal, and the two elastic parts are elastically contracted under extrusion, so that the fish eye terminal is smoothly inserted into the conductive hole of the circuit board, thereby realizing the electrical connection of the fish eye terminal and the circuit board. In the prior art, the traditional solid fish eye terminal is mostly H-shaped, that is, fish eye grooves are formed on both sides, and the middle is a "I" shaped structure, for example, the solid fish eye terminals disclosed in the patents CN118431790A, CN118040360A and CN219801298U. The strength of the solid fish eye terminal with the H-shaped structure is low, and after being pressed into the conductive hole of the PCB, it is easily extruded by the hole wall to produce irregular deformation, and in severe cases, it may be broken. The design of the fish eye terminal for automobile needs to consider the running conditions of the automobile in various harsh environments, including temperature change, vibration, humidity, etc., so the strength of the terminal has higher requirements, and the traditional H-shaped solid fish eye terminal cannot meet the use requirements.
